Platy is a common name for two related species of freshwater fish in the genus Xiphophorus. Both species are livebearers, similar to other fish of the family Poeciliidae, such as the guppy and molly. Platies are native to the east coast of Central America and southern Mexico.
The two species, the southern platyfish and the variatus platy, have been interbred to the point where they are difficult to distinguish. Most platies now sold in aquariums are hybrids of both species.
The southern platyfish (Xiphophorus maculatus) grows to a maximum overall length of 6.0 cm (2.4 in). Sexual dimorphism is slight, the male's caudal fin being more pointed. The anal fin of the male fish has evolved into a gonopodium, a stick-shaped organ used for reproduction. The female southern platyfish's anal fin is fan-shaped. Wild varieties are drab in coloration, lacking the distinctive dark lateral line common to many Xiphophorus species.
The variatus platy (Xiphophorus variatus) grows to a maximum overall length of 7.0 cm (2.8 in). In the wild they are olive in color with black marbling or spots on the side of the caudal peduncle. Large males show blackish blotches on the dorsal fin. Unlike some other members of the genus, X. variatus has no claw at the tip of the fifth anal fin ray. The fourth pectoral ray shows well-developed serrae (i.e. saw-like notches). They typically have 20 to 24 lateral scales, 10 to 12 dorsal rays and two rows of jaw teeth.
Mollies (Poecilia) are a genus of fish in family Poeciliidae of order Cyprinodontiformes. They are native to fresh, brackish and salt water in the Americas, and some species in the genus are euryhaline. Live-bearers, the Poecilia species are collectively known as mollies, with the exception of Endler's livebearer (P. wingei) and the famous guppy (P. reticulata). It has been proposed that the genus Micropoecilia should be included as a sub-genus of Poecilia.
Along with their platy cousins, the mollies are part of a pivotal aquaculture group of livebearers, which can live in water from fresh to fully marine, and a wide range of other conditions. They feed on smaller insects, animals, and vegetation.

《回家》这首乐曲作者为美国著名萨克斯演奏家凯丽金（Kenny.G)创作。其优美的旋律为全世界各地的人所熟知。也恰恰因为这首乐曲，让多数音乐爱好者了解并熟知萨克斯这一乐器。由于萨克斯本身声音悠扬清亮，而这首乐曲把缥缈缠绵的意境表现得相当到位。面对难以完美再现的萨克斯，尤其是清纯悠扬的清音效果和抒情的高音时，表现的完满而到位。层次感清晰分明，具有很强的感染力，音质柔和不显刺耳，却极富穿透力。回家乐曲中萨克斯的质感光可照人，铜味十足，回味无穷的音效性毫无保留的再现出来。一种真实感直冲而来，美丽，清秀，无杂的超空间立体感，尤其是里面的莎鼓和金锤等重金属的敲击声，细腻刚硬，延伸很远。给人以无限美好的遐想与向往。侧耳倾听，仿佛有了家的味道。

I took this video at the apartment of Nelson, my Chinese friend, in Flushing, Queens, New York City.

"I am very happy every day because I can watch the most beautiful aquarium, and listen to the wonderful music at home." Nelson, a Chinese young guy said.
